Yeah, that's a good way to put it. I can "feel" myself navigating my house in my mind, can draw a floor plan, etc., but I can't picture it. More like knowing "I can expect a chair there, or a wall there" or whatever.

I kind of suspect it might be similar to how blind people experience "visualizing" something where they've got the contours well-mapped in their head, but of course I have no way to know that for sure.
